Thanks for all the input. Yea, things are not so easy to get here and I don't make it to the mainland that often. Most of my stuff comes in via container from the US but takes several weeks.
I have managed to get everything glued and aligned (for the time being) using the ABRO epoxy clear with slightly more hardener. The test will be if everything is still in alignment on Saturday night!
I like the look of that 3M tape Jon - I may try and order a roll to use on the next upgrade.
Cheers
